I haven't been able to get ssh to forward X11 traffic. I also get no
errors that I can find.
I have "X11Forwarding yes" in sshd_config and login with `ssh -X
hostname` but `echo $DISPLAY` gives '0.0' after successful login.
I see no errors on either the server or client side or an any logs I
have looked into.
Is there a specific message I should see or process that I can see
created on the server or client side when this is working
correctly?
